Although there are plenty of methods for effectively imaging a 3D space, LiDAR is widely regarded as one of the most effective methods. These systems use a rapid succession of laser pulses over a wide area to create an accurate 3D map. Early LiDAR systems were cumbersome and expensive but as the march of time […]
There are a number of reasons you might want to build your own smart speaker virtual assistant. Usually, getting your weather forecast from a snarky, malicious AI potato isn’t one of them, unless you’re a huge Portal fan like [Binh Pham]. [Binh Pham] built the potato incarnation of GLaDOS from the Portal 2 video game […]
An occasional series of mine on these pages has been Daily Drivers, in which I try out operating systems from the point of view of using them for my everyday Hackaday work. It has mostly featured esoteric or lesser-used systems, some of which have been unexpected gems and others have been not quite ready for […]
[BorisDigital] was mesmerised by a modern elevator. He decided to see how hard it would be to design his own elevator based on Raspberry Pis. He started out with a panel for the elevator and a call panel for the elevator lobby. Of course, he would really need three call panels since he is pretending […]
The phones most of us carry around in our pockets every day hold a surprising amount of computing power. It’s somewhat taken for granted now that we can get broadband in our hands in most places; so much so that when one of these devices has reached the end of its life it’s often just […]
You don’t see them as often as you used to, but it used to be common to see “electronics trainers” which were usually a collection of components and simple equipment combined with a breadboard, often in a little suitcase. We think [Pro Maker_101’s] portable electronics workstation is in the same kind of spirit, and it […]
One of the most exciting trends we’ve seen over the last few years is the rise of truly personal computers — that is, bespoke computing devices that are built by individuals to fit their specific needs or wants. The more outlandish of these builds, often inspired by science fiction and sporting non-traditional layouts, tend to […]
Recently Raspberry Pi publicly announced the release of their new rpi-image-gen tool, which is advertised as making custom Raspberry Pi OS (i.e. Debian for specific Broadcom SoCs) images in a much more streamlined fashion than with the existing rpi-gen tool, or with third-party solutions. The general idea seems to be that the user fetches the […]
The MintyPi was a popular project that put a Raspberry Pi inside an Altoids tin to make a pocketable gaming handheld. Unfortunately, it’s not the easiest build to replicate anymore, but [jackw01] was still a fan of the format. Thus was born the Pi Tin—a clamshell handheld for portable fun! Neat, huh? More pocket-sized than […]
Back in 2023, we first brought you word of the PiEEG: a low-cost Raspberry Pi based device designed for detecting and analyzing electroencephalogram (EEG) and other biosignals for the purposes of experimenting with brain-computer interfaces. Developed by [Ildar Rakhmatulin], the hardware has gone through several revisions since then, with this latest incarnation promising to be […]
